Description
Technical field
The invention belongs to changing rejected material to useful resource processing technology fields, and in particular to give up sugar in a kind of sucrose trichloride production process
The recycling processing method of liquid.
Background technique
Sucralose is the functional sweetener using sucrose as raw material, and in its production process, 1 ton of product of every acquisition is about
It can generate useless sugared (chlorinated sucrose and the chlorinated sucrose ester waste) of 1.5-3 tons of dry matter equivalents, the useless sugared dry matter heat of per kilogram
Value is about 4000 kilocalories.The stock solutions that the waste liquid or crystallization and purification that these useless sugar major parts are obtained with extraction and separation obtain are deposited
, therefore waste saccharide liquid caused by Sucralose per ton is produced up to 4-15 tons of waste saccharide liquids, CODcr is generally up to hundreds of thousands of millis
Gram per liter.Since waste saccharide liquid quantity is big, COD value is high, it is processed into for one in Sucralose environmental protection of enterprise control
Priority and difficulty problem, or even influence the sound development of Sucralose industry.
Since waste saccharide liquid has the feature of high cod values and its chlorine-bearing compound biodegrade hardly possible, waste saccharide liquid is diluted laggard
Row sewage treatment is unpractical.It is the more satisfactory approach of one kind (assuming that waste saccharide liquid CODcr by waste saccharide liquid progress burning disposal
It is 14KJ calculating by 1 gram of CODcr organic matter heat for 300,000 mg/L, then per kilogram waste saccharide liquid can produce 1000 kilocalorie heats, because
This can both realize environmental protection treatment using its heat generated by burning, and go back escapable cost).However since waste saccharide liquid high temperature fires
Releasably a large amount of chlorine, the hydrogen chloride further generated by chlorine can be to burning facility generation heavy corrosions, if do not located when burning
Reason can also bring secondary pollution problem, and the Chlorobenzens further generated by chlorine are then environmental carcinogen dioxin-like chemical
(PCDD/Fs) important precursor needs further to take measures to prevent and reduce the generation of dioxin-like chemical, or
The burning for taking measures to remove before flue gas emission, therefore directly carrying out waste saccharide liquid has high in burning facility and technical aspect
It is required that furthermore the chlorinated sucrose ester in waste saccharide liquid has low aqueous solubility and high-adhesiveness, difficulty is also brought along on burning conveying,
So directly carrying out burning disposal to waste saccharide liquid is being currently the problem of industry.
Summary of the invention
For the intractable status of waste saccharide liquid in above-mentioned sucrose trichloride production process, the purpose of the present invention is to provide one kind
The recycling processing method of waste saccharide liquid in sucrose trichloride production process, this method is simple, economic, at the environmental protection for realizing waste saccharide liquid
It can achieve the effect that recycling while reason.
Above-mentioned purpose of the invention can be achieved through the following technical solutions: give up sugar in a kind of sucrose trichloride production process
The recycling processing method of liquid, comprising the following steps: choose waste saccharide liquid, lime or lime slurry is added, carried out at 60~108 DEG C
Processing, obtains the suspension containing dechlorination organic matter.

With.
Preferably, auxiliary material or internal combustion of the suspension containing dechlorination organic matter in including but not limited to fuel coal water slurry
The application baked bricks in terms of material.
Basic principle of the invention is to generate hydrolysis using calcium hydroxide and waste saccharide liquid, and the sugar hydrolysis dechlorination that gives up generates de-
Chlorine organic matter and calcium chloride can when then waste saccharide liquid processed by the invention burns as auxiliary material since calcium chloride is non-combustible matter
It avoids effectively mitigating hydrogen chloride bring relevant issues, to achieve the purpose that waste resource recovery utilizes.
The present invention have it is following the utility model has the advantages that
(1) chlorinated sucrose, the chlorinated sucrose ester in waste saccharide liquid are carried out water using cheap raw material by the method for the present invention
Dechlorination is solved, is obtained by dechlorination organic matter, the mixed reactant of calcium chloride, calcium hydroxide and water composition, due to the generation of calcium chloride,
So that originally can with waste saccharide liquid burn and discharge chlorine be fixed, efficiently solve the problems, such as waste saccharide liquid for burning it is secondary;By
It is fixed in originally flammable chlorine, treated waste saccharide liquid recycling is used for auxiliary combustion as auxiliary material, raw material, both realizes
Being effectively treated for useless sugar, will not bring secondary pollution, and can produce certain economic benefit;Such as the auxiliary material as water-coal-slurry,
Dechlorination organic matter burning therein is generated compared with high heating value, can correspondingly save fuel, calcium chloride therein is conducive to water-coal-slurry
Dispersion and stablize, calcium hydroxide therein plays the role of adjusting water-coal-slurry pH, and can generate in combustion system fixation chlorine from
The harmful substances benefit such as son, sulfur dioxide uses water when water therein directly can replace preparing water-coal-slurry, can correspondingly reduce water
Dosage;
